Effects of Light on Production of Toxins by Helminthosporium victoriae and H. carbonum
Cho Eui Kyoo,Scheffer Robert P. Korean Society of Applied Entomology 1975 한국식물보호학회지 Vol.14 No.2
Helminthosporium vicotoriae and H. carbonum were grown under fluorescent plus incandescent lights, or in darkness, with several different temperature regimes. There was little or no effect of light on toxin production by H. victoriae. Light-grown cultures of H. carbonum had significantly higher titres of host-specific toxin than did dark-grown cultures. Light had no significant effect on growth of either fungus. Maximum titres of host-specific toxins from both fungi were evident at the time maximum growth was reached. Minimum pH values in Fries modified medium occurred at the time of, or slightly before maximum level of toxin was reached.

BackgroundCytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are high-risk extensive abdominal surgery. During high-risk surgery, less invasive methods for cardiac index (CI) measurement have been widely used in operating theater. We investigated the accuracy of CI derived from different methods (FroTrac, ProAQT, ClearSight, and arterial pressure waveform analysis [APWA], from PICCO) and compared them to transpulmonary thermodilution (TPTD) during CRS and HIPEC in the operative room and intensive care unit (ICU).MethodsTwenty-five patients scheduled for CRS-HIPEC were enrolled. During nine predefined time-points, simultaneous hemodynamic measurements were performed in the operating room and ICU. Absolute and relative changes of CI were analyzed using a Bland-Altman plot, four-quadrant plot, and interchangeability.ResultsThe mean bias was −0.1 L/min/m2 for ClearSight, ProAQT, and APWA and was −0.2 L/min/m2 for FloTrac compared with TPTD. All devices had large limits of agreement (LoA). The percentage of errors and interchangeabilities for ClearSight, FloTrac, ProAQT, and APWA were 50%, 50%, 54%, 36% and 36%, 47%, 40%, 72%, respectively. Trending capabilities expressed as concordance using clinically significant CI changes were −7º ± 39º, −19º ± 38º, −13º ± 41º, and −15º ± 39º. Interchangeability in trending showed low percentages of interchangeable and gray zone data pairs for all devices.ConclusionsDuring CRS-HIPEC, ClearSight, FloTrac and ProAQT systems were not able to reliably measure CI compared to TPTD. Reproducibility of changes over time using concordance, angular bias, radial LoA, and interchangeability in trending of all devices was unsatisfactory.
Morphological traits of stem to indirect selection of resistance to lodging in Avena sativa L

The runout of newly cultivated areas in the world without recurring to the deforestation, demand a necessity to improve yield to sustain a growth population which demands each time more food. To avoid that is necessary to solve the main issues which cause crop productivity reduction, such as lodging which causes yield reduction in many major crops such as wheat, barley, rice and oat. In this sense, a study with eight cultivars evaluated morphological traits of the stem as crown diameter, internal and external diameter of the frst four basal internodes, the length of internodes, peduncle and panicle, plant height, and also lodging resistance factor (cLr), green and dry panicle matter. The diameter of the crown does not show diferences among the cultivars, the morphological characters which showed correlation and relative contribution with cLr were the internal and external internodes diameters, showing their capacity to be one of morphological traits of the stem to an indirect selection of resistance to lodging in Avena sativa L. The length did not show a good correlation with lodging, probably due to the fact that this trait was the focus of breeders for many years, reaching the plateau, demanding focus in other traits to avoid lodging such as interna and external diameter of internodes. The cultivar URS Brava and IPR Afrodite demonstrated to be a source of lodging resistance in oat.
